The diameter of a circle is twice its radius

The circumference of a 144-inch diameter circle is about 452.4 inches. (C = d x Pi).
The formula for calculating the area of a circle is 'pi r squared,' where 'r' represents the radius of the circle. A radius of a circle is, of course, half its diameter. Therefore, divide the diameter (24) by 2, then square it, then multiply that figure by pi. Twenty-four divided by two is twelve. Twelve squared is 144. So, multiply 144 by pi and 'Bob's your uncle.'
you take the diameter and divide it in half then you have the radius. Take the radius and multiply the radius by its self (radius squared) then multiply by 3.14 (pi) example: Diameter is 24 find the area. 24 divided by 2 is 12 12x12= 144 144x3.14= 452.16
The only shape that can do that is a circle.Circumference = 24.Diameter = 24/piRadius = 12/piArea = pi R2 = 144/pi = 45.837
If 12x12 is 144... There would be 144 tiles in a box right?
